On the other hand, in the massage section 2, a roller case 7 as a first rotating disk is fixed to the shaft 6 by screws 8. In addition, 9 is a washer. Here, as shown in FIG. 2 and FIG.
In the vicinity of the edge of the first roller 1, a plurality of, in this embodiment, three first rollers 1 horizontally supported so as to rotate in parallel with the shaft 6.
Zeros are provided at predetermined intervals, and a part thereof protrudes from the lower surface of the roller case 7.

Above the edge of the roller case 7, a plurality of, in this embodiment, three second rollers 11, which are vertically supported so as to rotate in parallel with the roller case 7, are arranged at predetermined intervals. And a portion thereof is provided to protrude laterally from the edge of the roller case 7.

As shown in FIG. 3, the roller case 7 has three holding grooves 7a for holding a horizontal shaft 12 which supports the first roller 10, and also supports the second roller 11. Three holding holes 7b for holding the vertical shaft 13
Are provided respectively.

Incidentally, a roller holder 14 as a second rotating disk is disposed opposite to the roller case 7.
Here, the roller holder 14 is fixed to the roller case 7 by a fixing screw 15 and rotates together with the roller case 7, while holding the first roller 10 and the second roller 11 rotatably together with the roller case 7. Things.

For this reason, the roller holder 14 is provided with three ribs 14a for holding the horizontal shaft 12 at three places, and three holding holes 14b for holding the vertical shaft 13.
It is provided in each place.

Then, the roller case 7 and the roller holder 1
4 are fixed by fixing screws 15, the three horizontal shafts 12 are held by the holding grooves 7a of the roller case 7 and the ribs 14a of the roller holder 14, respectively. Further, the three vertical shafts 13 are respectively provided in the holding holes 7 b of the roller case 7.
